    Another winterize question

    Seems like a huge waste to do anything on a full system. What are you protecting? Risers? Hx? Even a ½ system I really doubt you'll be extending manifold life significantly with a/f vs. just a fresh water flush.

    Wow, @tpenfield , those are awesome diagrams. I daresay they're sticky worthy, @GA_Boater

    Running lean after engine swap

    I'm running the stock 5 mmhg spring. So it's not getting rich until nearly WOT. Haven't checked the advance. I'm running the exact same prop and drive that I had on my 3.7. With better compression and 50 more hp, I should be doing better. Trim is the same, though it doesn't feel like I'm able...

    4.3L intake manifold drain?

    I've seen discussion about an intake manifold drain that needs to be pulled to winterize the 4.3L vortec. I don't see a super obvious drain plug on mine, and can't find anything in the manual about it. Could someone point me in the right direction? Pic is of my intake manifold, the only thing...

    Drive removed for the 1st time, gimbal aligment inspection

    Looked like you had a much harder time on video #2 than 3? Try using a lot less grease on the tool. A very thin layer is enough.

    Running lean after engine swap

    @Rick Stephens Worrying less now, working on tuning. Might have imagined it anyways. Those plug pulls were actually from last time out, which was a similar run with flooding at the end. I'm still a step lean on the secondaries from stock. I could also try some stiffer springs, which would get...

    Running lean after engine swap

    Ok, another update. Got my cheap digital tach working, and came up with these numbers: 3200 rpm / 32 mph / 11 mmhg 3500 rpm / 36 mph / 7 mmhg 4k /42 mph / 5-6 mmhg Wot 4500 rpm / 4-5 mmhg I thought I heard it ping a couple of times at wot. I'm going to fatten up the secondary jets and see...

    Nola Mike's 3.7/470 --> 4.3L swap thread

    Got my induction cheapo tach to work (I also got a slick bluetooth dvm that can measure hz, so I'm going to see if I can get some reliable readings from that). my boat tach does indeed seem to get worse with increasing rpms. Now speeds are looking just like they were with the old motor, 1...

    Mercruiser 470, 2 to 4 barrel carb conversion.

    @Lou C is back! I was pleased with myself that I put in a remote oil filter and drain.

    Mercruiser outdrive horizontal alignment

    Book answer is that horizontal misalignment shouldn't happen, though I and a few others have had it happen. First steps would be to check your rear mounts and check your transom and stringers for rot. I'm not sure, but suspect that uneven front mount height can do it as well.

    Mercruiser 470, 2 to 4 barrel carb conversion.

    I know. Dontcha think I had enough headaches with the install? I still probably can if need be, I have the hx. I'll see how bad winterizing actually is.

    Drive removed for the 1st time, gimbal aligment inspection

    I hear you. But spline marks can be misleading (in my case I had a horizontal bias as well), whereas resistance to turning/insertion is ultimately what you're trying to reduce. And I think turning resistance is easier to feel than insertion. Just saying that both can be useful.

    Mercruiser 470, 2 to 4 barrel carb conversion.

    I liked mine. Never had a 470 specific issue in 12 years. Never had a HG blow, never overheated. Cam shaft seals original. Did have the regulator blow, but the original lasted 25 years. Components more accessible than a vee, and cheaper since you only have to buy one set (assuming they aren't...

    Drive removed for the 1st time, gimbal aligment inspection

    I found that turning the tool helped things a lot when I was installing my engine. Even if the spline marks looked the same, I could feel a difference. Also I think it makes sense since what you're after is to limit the stress on the coupler.

    Mercruiser 470 head and gasket inspection

    Agreed, that shot of the head. Less likely that you'd have a cracked head/block, though certainty possible

    Winterizing involves pulling the aft plug on the hx...1 minute if you're missing 3 fingers

    Forum update

    Can't Yup, exactly that. Rotating it shows them. Rotating also shows who the last post was from (which I commented on earlier) Not quite, see above. Plus I'm getting good at multi quotes
